US stocks are struggling with compressed valuation multiples and weak corporate performance as the market prepares for the first quarter of 2026 earnings season.
According to Goldman Sachs Group Inc.'s (NYSE:GS) latest "Weekly Kickstart" report, the S&P 500 has fallen 9% from its January highs, largely driven by soaring oil prices, rising interest rates, and ongoing instability caused by the Iran war.
The benchmark index's price-to-earnings (P/E) multiple has fallen from 21x to 19x over the past month, even as analysts paradoxically raised their 2026 earnings per share (EPS) forecasts by 3%.
Technical Sentiment and Fundamental Strength
From a technical perspective, the sharp decline in market positioning points to a potential reset in investor sentiment. Goldman's US Equity Sentiment Indicator fell to -0.9, the lowest since August 2025. Historically, readings below -1 have preceded above-average returns.
However, analysts warn that current positioning is likely insufficient to trigger a rally without a clear improvement in the fundamental outlook. Market valuations of economic growth point to further downside potential for stocks if the regional conflict in the Middle East continues to escalate.
The fundamentals of US corporations remain strong despite macroeconomic headwinds. Goldman Sachs maintains its baseline earnings per share growth forecast for the S&P 500 at 12% in 2026, assuming the current turmoil does not become overly protracted. The upcoming earnings season will be a critical test of the bank's optimism, as investors seek evidence that companies can maintain margins amid high energy costs and shifting global trade routes.
Political Impact and Market Trajectory
The market is now awaiting the Federal Reserve's response to the stagflationary pressures of the Iran war. Corporate profits are rising, but the combination of high oil prices and persistent inflation has complicated the path to potential rate cuts.
Investors are increasingly favoring companies with high quality metrics and strong balance sheets capable of withstanding a higher-for-longer interest rate environment.
As first-quarter earnings reports emerge, the ability of management teams to provide reliable guidance amid regional instability will determine whether the S&P 500 can find a bottom at current levels.
